android - 如何从 fragment 获取getSupportFragmentManager()

getSupportFragmentManager在片段内部不起作用

Fragment tFragment = MainActivity.newInstance();

        FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
        ft.replace(R.id.frame_container, tFragment);
        ft.commit();

任何答案都是可观的

最佳答案

private FragmentActivity myContext;

覆盖片段的onAttach方法：

@Override
public void onAttach(Activity activity) {
    myContext=(FragmentActivity) activity;
    super.onAttach(activity);
}

当您需要获取支持片段管理器时，请致电：

FragmentManager fragManager = myContext.getSupportFragmentManager();

要么

FragmentManager fragManager = getActivity().getSupportFragmentManager();
